[thelist] javascript & forms

james,

: is there a way to catch when someone types a return
: character into a text field in a form?
:~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

one way would be to simply put an additional form on the page, then the
enter key will no longer work as a submit (so they say).

:~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
: They never wind up in the value of the form element - I'd
: like to catch when someone types it and adjust the focus
: of the document ...
:~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

just do a simple onSubmit validation, returning false if the form doesn't
have anything entered in it.

<SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript">
  <!--
    function validateForm(form)
    {
      if(form.username.value == '')
      {
        alert('This field is required.  Please enter your username.');
        form.username.focus();
        return false;
      }
      else
      {
        return true;
      }
    }
  // -->
</SCRIPT>

then, your form might look like this:

<FORM
  NAME="myLogin"
  onSubmit="return validateForm(this)">
  <INPUT
    TYPE="TEXT"
    NAME="username"
    SIZE="10"
    VALUE="">
</FORM>


good luck,
